'To all whom t may concern.'

Be it known that we, DANIEL L. EVANS and FRANK A. PHILLIPPI, citizens of the United States,'residing in Pottstown, Montgomery county, State of Pennsylvania; have invented Coolers, of which the following is a speciication.'

One object of our invention is to provide af-compact, substantial and relatively eflicient device for coolingy suchl liquids as water, beer, etc., which shall be inexpensive to manufacture, simple in construction and easily cleaned, and whose interior parts are so mounted as to permit of their quick and convenientJ remova'l and replacement.

These objects and other advantageous ends we secure as hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a vertical section of a cooler constructed according tov our invention; and

Fig. l2 is a transversefsection on the line 2- 2, Fig. 1. f

In the above drawings, 1 represents a more or less elongated, substantially cylindrical casing preferably thoughy not Anecessarily made of some non-corrosive metal such as tin, tinned brass, etcl, and having la base 2 to which it is secured. This base is formed with an integral or other suitably connected conduit 3 forming an outlet in-the case illustrated and opening into the interior of the casing at the center of said base. The upper end of the casing is provided with a collar 5al preferably sweated or soldered in place and provided at one side with a tubular boss 5 constituting an inlet.

From this collar 5a project lugs 4 to which are pivoted threaded bolts 4a for the reception of thumb nuts 6 designed to engage forked lugs 7 projecting from a clamping plate 8 designed to hold a cover plate 9 againstthe open end of the casing, there being vpreferably a gasket of suitable material between the end of the latter and said cover plate.

Within the casing we mount a frame consisting of top and bottom plates 10 and 11 connected by four or any other suitable number of sets of guide rods 12 and 14 which are sweated to said bottom plate and at their upper ends passed through the top plate which is removably held in place ata level slightlyv below the inlet 5. Said latter' plate closely ts the interior of the casing and has a centrally placed openingfor the i-deliveryfof.. liquid into' the mainportion of the. casing. yThe platev 10 is maintainedy on the rods 12 and 14 by, spherical thumb nuts threaded thereon.

rllhe two rods 14 engage opposite points of the two removable plates 10 and 11 at equal distances from .the center .thereofwhich preferably lies in the central line'of `the casing and .on them are mounted la series of sub-stantially spherical baffle structures 15 of porcelain, glass, cement, non-corrosive metal, earthenware, etc., which while shown asrhaving 4annular grooves 16 may be made whol'ly spherical as in the case of `asimilar series of balls or spheres 17 mounted" on the rods 12. While the dimensions of the baffle structures 15 and 17 maybe widely varied,

'wev preferably f make thern ofj diameter somewhat less than the radius of the casing vand so mount the rods 12 and 14 that the distance between opposite rods is somewhat greater than said radius. Moreover the baffle structures 15 and 17 are staggered or alternated and with the arrangement shown ofthe casing.

With the described arrangement of parts, when the cover and clamping plate are secured in position, liquid admitted to the inlet 5 is delivered to the center of .the top of the casing whence it is caused to follow a tortuous path in flowing down and around the various baffle structures and tends to form eddies around them as well as in the annular grooves of the structures 15 so that its passage is delayed sufficiently to permit it to be cooled to a relatively low temperature, it being understood that under conditions of use the casing is placed in a vessel containing ice or other refrigerating means.

When it is desired to clean or inspect the condition of the cooler, the cover plates may be easily removed by backing Off the thumb nuts and swinging the hinged bolts away from the frame, after which the rods 12 and 14 with their plates and bafle structures may be easily .removed from the casing. Since are practically tangent to the inside surface f Specification of Letters Iiaitent.l i: Patented 19, 1919. d i

opiel of this patent may be obtained for said baiiie structures are made with grooved surfaces and'round edges theyl do not tend to collect solid material and when desired may be perfectly cleanedwith the greatest` ease especially since they may be'rotated upon the rods 12 and 14: in order toexpose their inner portions. y Obviously without vdeparting from our invention the shape of the baiie structures may be .considerably modified and if desired they may be all of val 'spherical formor all provided with annular grooves .16. ln any case they are preferably arranged in alternate setsfrom one end lto the other of the casan inlet and an outlet;with a series of subv stantially sphericaly balile structures in the casing; and a frame engaging said structures for simultaneously removing the same.

'2. The combination ina cooler of a casing; a plurality 'of guide rods mounted in said casmg; and series of overlapping baile ing; a plurality ofv guide rods extending ylongitudinally of said casing; andl substan- 'tially spherical baillev structures rotatably mounted on said rods.

4f. The combination in a cooler of an elongated substantially cylindrical casing having a removable covejr and provided with an inklet andoutlet at relatively distant points; a

removable frame in the casing including guide rods extending longitudinally thereof;

V with a series of spherical structures ofwvitreous material rotatably mounted onsaidV rods in relatively staggered sets and substantially tangent to the inner surface of the casing.

5. The combinationof a casing having an inlet and outlet; with a series of substantially spherical baiie bodies having annular grooves and mounted inthe casing in position .to provide tortuous channels between the inlet `and outlet with a structure for definitely positioning said bodies in said casing. v l 6.k The combination in a cooler ofan elongated easing having an inlet and an outlet' at relatively distant points; a plurality of rods extending longitudinally -of said casing; Vseries of overlapping baille structures respectively mounted on said rodsg-with a plate having a central opening and inter-y posed between one of the openings of the casing and said baiile structures. structures rotatably mounted on said rods.
